Vivid memory - it's almost like a photographic memory.
Profession:
Elderly. Educates the younger generations on the apocalypse.
Background:
One day at school was enough for him to want to change his name. "Lake, Tahoe" became Tom. For a few months. When the apocalypse hit, suddenly he was glad to have such an unusual name. After all, the man-made Lake Tahoe was no more. Tahoe felt like he had to educate everyone with what happened. Maybe it didn't work so well, but his son and granddaughter turned out alright. Crystal seemed like a good person to continue on with his teacheing.
